Answer:
12 minutes
Step-by-step explanation:
Let c and h represent the filling times for the cold and hot taps, respectively. When the cold tap is 1/2 open, we presume that means the filling time becomes 2c.
In terms of baths per minute, the relationships are ...
1/c + 1/h = 1/3
1/(2c) +1/h = 1/(3 +1.8) . . . . . 1:48 min:sec is 1.8 minutes
Subtracting the first equation from twice the second, we get ...
2(1/(2c) +1/h) -(1/c +1/h) = 2(1/4.8) -(1/3)
1/h = 2/4.8 -1/3 = 1/12
h = 12
It takes the hot tap 12 minutes to fill the tub alone.
Go to a math calculator and type this in then press graph and it will give you your answer
Answer:
y = -2x - 2
Step-by-step explanation:
Slope intercept form of equation is y = mx + c
c is intercept and m is slope
given that slope is -2
m = -2
thus, equation in slope intercept will be
y = -2x + c
The given line passes through (-1,0)
y = -2x + c
lets substitute y = 0 and x = -1 in the given equation
0 = -2*-1 + c
0 = 2 + c
c = -2
Thus, the complete slope intercept equation after using the value of c as -2
we have
y = -2x - 2 answer
